SIMON DELIZE, OF VEVVIERS, BELGIUM.

IMPROVEMENT IN COTTON OPENING AND LAPPING MACHINES.

Specification forming part of Letters Patent No. 5!,962, dated June 16, 1874; application filed April 11, 1874.

To all whom it may concern:

Be it known that I, SIMON DELIZE, of Vevviers, in the Kingdom of Belgium, have invented certain new and useful Improvements in Machines for Preparing \Vool, Cotton, and other Fibrous Material; and I do hereby declare that the following specification, taken in connection with the drawing making a part of the same, is a full, clear, and exact descrip tion thereof.

The drawing exhibits a perspective view of the entire machine.

The invention hereinafter described is an improvement upon the machine described in the Letters Patent of the United States granted to me as assignee of Alexander Joseph Deru, dated April 21, 1868, and to which Letters Patent reference may be had.

The object of my machine is to produce a sheet of lapping of regular thickness and uniform density, which shall be in proper condition to be afterward fed, automatically, to the cardin machinery.

In machines of this class the wool or other fibrous material is thrown, by the action of beaters revolving at a high degree of speed, within an inclosed case upon an endless apron, which forms the bottom of a box, the interior dimensions of which determine the width and thickness of the sheet of lapping. It is important that the density of the lap should be uniform, and in the means to effectually secure this consists my invention.

In the drawing, A is the flame-work of the machine. B is an endless apron, which forms the feeding-table, and is drawn ata regular rate of speed by any convenient system of gearing deriving movement from the prime mover. The fibrous material is deposited in a mass upon this apron, and is distributed by an attendant, so as to pass with some degree of uniformity between a pair of feedingrollers, one of which is shown at O, and which obtain their movement, in any convenient way, from the prime mover. The fibrous material taken between the feeding-rollers is delivered inside the beater-cylinder 1), in the usual way. Inside this cylinder a set of heaters, consisting of fans attached to radial arms on the shaft E, andprovided with teeth similar to those shown in the drawings attached to the patent before referred to, are made to revolve with a high degree of velocity by means of a belt passing over a drivingpulley upon the end of said shaft E. The material is acted upon by the revolving heaters, and delivered upon the endless apron F, which forms the bottom of the box G in the form of a lap, from whence it is delivered in a sheet and wound up on a cloth into a roll, II.

If this were all, the machine would be substantially like machines for a similar purpose known in the art to which it belongs.

The rcvolving fans upon the beater-arms create a powerful blast of wind, the pressure of which should be uniform, as upon its intensity depends the density of the lap which is formed inside the box G. Accordingly, I have made the casing I, which surrounds the heaters, perforated with holes for the escape of a portion of the blast generated by the revolving fans, and have combined with the same and with the main exterior casing a valve, J, which opens to allow of the escape of the air when the pressure created by the blast is in excess of the requirements. It follows that the form of the blast, which is the active agent or means for depositing the fibrous material upon the apron in the box G, is constantly regulated by means of the escapevalve J. which latter can be made, by means of an adjustable weight or spring, to exert any prescribed degree of resistance to the blast.

In practice, I prefer to adjust the valve so that it will be half open when the lap has halffillcd the box G, and thus its position is a guide to the attendant in feeding the machine.

The box G, within which the lap is formed, may also be perforated with holes through the top, the ends, or through the apron, according to the judgment of the constructer.

\V hat I claim as my invention, and desire to secure by Letters Patent, is-

The combination, in a lapping-machine, of the escape-valve J, the perforated casing I, inclosing suitable revolving beaters and fans, and a suitable box, G, within which the sheet of lapping is formed, substantially as described.

S. DELIZE.
